Campers have been using pop-up campers for years, now they can use a pop-up grill. Helping campers make room in their already stuffed-to-the-roof-lining cars, the Pop Up Grill serves as both charcoal grill and campfire grate, providing two ways of cooking smoky meals. Leave the charcoal at home and cook right over the campfire or use it as a traditional charcoal grill.
